+config BLK
+       bool "Support block devices"
+       depends on DM
+       default y if DM_MMC
+       help
+         Enable support for block devices, such as SCSI, MMC and USB
+         flash sticks. These provide a block-level interface which permits
+         reading, writing and (in some cases) erasing blocks. Block
+         devices often have a partition table which allows the device to
+         be partitioned into several areas, called 'partitions' in U-Boot.
+         A filesystem can be placed in each partition.
+
+config AHCI
+       bool "Support SATA controllers with driver model"
+       depends on DM
+       help
+         This enables a uclass for disk controllers in U-Boot. Various driver
+         types can use this, such as AHCI/SATA. It does not provide any standard
+         operations at present. The block device interface has not been converted
+         to driver model.
+
+config BLOCK_CACHE
+       bool "Use block device cache"
+       default n
+       help
+         This option enables a disk-block cache for all block devices.
+         This is most useful when accessing filesystems under U-Boot since
+         it will prevent repeated reads from directory structures and other
+         filesystem data structures.
